Development and Evaluation of a VR Training Simulator for Posterior Cervical Fusion
Posterior cervical fusion is a procedure in which screws are inserted into the vertebral arch root, which is a part of the spine, to fix the spine and correct deformities. However, because the vertebral arch root is thin and surrounded by many nerves such as arteries and spinal cord, care is required when inserting screws to avoid damage during surgery.
In this study, we utilize virtual reality (VR) to present visual information with depth using a head-mounted display (HMD) and tactile sensation of the bone using a force tactile device. We aim to develop a simulator that can train residents to repeatedly perform screw insertion and planning of the screw insertion route by creating an environment similar to that of a real surgery.
Devising and evaluating a visual presentation method for communicating the degree of force for skill transfer.
As the population continues to age and the birthrate declines, it is becoming increasingly difficult to secure skilled personnel in the small and medium-sized manufacturing industry every year. Skills accumulated over many years are the strength of small and medium-sized manufacturing industries, and a shortage of skilled personnel could jeopardize the survival of small and medium-sized manufacturing industries. As a solution to this problem, a learning method has been devised that aims to efficiently acquire skills by imitating and training preserved skilled skills using a VR space.
This study focuses on "force", which is difficult to observe in skill transfer, and develops a VR simulator for training that can easily and efficiently imitate force using visual and haptic feedback in a VR environment by using a haptic device.
